The Study Of Correlation Of The Between Operative Treatment And Influencing Factor Of Thoracic Spinal Stenosis

Objective：To observe the surgical outcomes of TSS patients, and to carry outsurgery-related factors and statistical analysis to explore the impact of surgical treatment ofpatients with thoracic spinal stenosis related indicators for predicting clinical surgery, toprovide a reference guide postoperative rehabilitation.Material and Mehtods：Select from September2009to July2013in our hospitalbecause of thoracic spinal stenosis underwent surgery38patients were retrospectivelyanalyzed, including22males and16females; aged44-76, mean58.5±8.4; The averagefollow-up time of24.3months. On the medical records of patients to collect and organize,follow-up survey lines, physical examination and so on.(1) According to whether patients with spinal trauma-related factors are combinedspinal-related diseases, MRI T2-weighted images high signal spinal whether there will be thisgroup of patients were divided into two groups using independent sample t tests werecompared postoperative improvement rate in each group have no difference in the impact ofthese three factors to determine the efficacy of surgery.(2) Application Pearson correlation analysis, correlation analysis of postoperativeimprovement rate before the former age, duration of surgery, preoperative JOA score, canalarea residual rate of each index to determine its impact on surgical outcomes.(3) logistic regression analysis to further clarify the factors associated with postoperativepatient-related improvement rate.Using SPSS17.0statistical software for statistical analysis, P <0.05as statisticallysignificant criteria.Results：(1) There are spine-related trauma group before preoperative JOA score nolower than the trauma group, but the difference between postoperative improvement was nosignificant difference (P>0.05).(2) in combination with other groups of patients with spinal lesions preoperative JOAscore lower than those without complications, but the difference between postoperativeimprovement was no significant difference (P>0.05). (3) on the front of preoperative MRI T2hyperintensity group preoperative JOA score nolower than the high signal group, and a significant difference (P <0.05), but no difference wassignificant postoperative functional improvement rate (P>0.05).(4) Correlation analysis showed a significant correlation between the patients beforesurgery to improve the rate and duration of disease, spinal area of the residual rate. And withage, no correlation was significant between preoperative JOA score.(5) Multiple linear regression analysis showed that postoperative improvement rateamong the most significant factors in patients with preoperative course and canal area of theresidual rate and draw the regression equation: improvement rate (IR)=0.2-0.01×duration+0.008×vertebral tube area residual rate.Conclusion：Preoperative course, the residual rate of thoracic spinal canal area stenosisis an important factor affecting the efficacy of postoperative patients, can be used asindicators to predict postoperative function. However, the patient’s age, spine-related trauma,spine-related complications, preoperative JOA score, high signal MRI T2-weighted imagescan not be used as predictors of surgical outcomes judgment.
